An Analysis of Power Friction Losses in Gear Engagement with Intermediate Rolling Elements and a Free Cage

open access: yesMathematics
Currently, mechanical gears with cycloid engagement are increasingly used in mechanisms along with involute ones. In modern drive mechanisms, using pin gears and gears with intermediate rolling elements (IRE) is widespread, which simultaneously use ...

Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

open access: yesJournal of Fish Biology, Volume 109, Issue 1, Page 371-383, July 2026.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Simulation Analysis of Meshing Characteristic for Cycloid Meshing Drive of RV Reducer

open access: yesJixie chuandong, 2017
The cycloid pin wheel drive is essential to RV reducer. It is the basic point to determine the contact stiffness of cycloid and pin wheel. The equivalent contact stiffness is calculated based on Hertz contact theory.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Remarkable Electric Field‐Controlled Magnetism in La/Sm Co‐Substituted BiFeO3 Multiferroic Ceramics

open access: yesAdvanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
The remarkable electric field‐controlled magnetism (change of Mr reaches up to 62.7%) in La/Sm co‐substituted BiFeO3 ceramics, originating from the electric field‐induced phase transition of Pna21/R3c, is achieved by enhancing the dielectric strength. Moreover, the significant improvement in ferroelectricity is also determined after the electric field ...
